The Metamorphic Petrology of Central Queen Maud Land - A Distinct Geologic Province in East Antarctica

该奖项支持矿物学，岩石学和地质年代学 对皇后地中部高级变质岩的研究， 南极洲东部前寒武纪地盾的一部分。 实地工作 将在1989-1990赛季结束。 校长 研究者已被指定为美国交换科学家， 苏联南极探险队 研究将集中在 变质沉积物： 不同的变质事件和流体条件， 特别是CO2在麻粒岩相变质作用中的作用。 地质年代学研究应该提供地质信息， 高级变质岩侵位前的历史 在6亿年前的长花岗岩和花岗岩中， 毛德皇后地不仅可以与 东南极地盾，还有南部非洲。

This award supports a mineralogic, petrologic, and geochronologic study of the high-grade metamorphic rocks of Central Queen Land, a portion of the East Antarctic Precambrian shield. Field work will be done during the 1989-1990 austral season. The Principal Investigator has been designated the U.S. exchange scientist with the Soviet Antarctic Expedition. Research will focus on the metasediments: the pressure-temperature conditions of the different events and fluid conditions of metamorphism, in particular, the role of CO2 in granulite-facies metamorphism. Geochronologic studies should provide information on geologic history of the high-grade metamorphic rocks prior to emplacement of pegamite and granite 600 million years ago, so that central Queen Maud Land can be correlated not only with other parts of the East Antarctic Shield, but also with southern Africa.
